The speed limit at the Gap was NOT set by a traffic survey. We're talking about a road with no intersecting roads, no driveways, no anything.

So seems like it's been set by the frequency of accidents. Yup, the more speed-related accidents the more the authorities want to lower the speed limit. And there are PLENTY of accidents resulting from people going faster than their skill level allows. As demonstrated on this thread. Since they can't administer road tests to everyone entering the area, instead they lower the speed limit.
